Which three options are supported when migrating to Autonomous Database (ADB)? (Choose three.)
Which three options are supported when migrating to Autonomous Database (ADB)? (Choose three.)
When migrating to Autonomous Database (ADB), three supported options include RMAN Cross-Platform backup and restore, PDB unplug/plug operation, and Datapump export/import. RMAN Cross-Platform backup and restore allow for a platform-independent backup and restoration process. The PDB unplug/plug operation enables the moving of a pluggable database from on-premises to the cloud. Datapump export/import is a widely used Oracle utility for high-speed movement of data and metadata between databases. These methods ensure a smooth and efficient migration to ADB.
Which two optimizations are different between Autonomous Data Warehouse and Autonomous Transaction Processing? (Choose two.)
Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP) differ mainly in how they handle data organization and memory usage. ADW is designed for analytical workloads and typically uses a columnar data store, which is optimized for query performance and complex aggregations. In contrast, ATP is optimized for transactional workloads and uses a row-based data store, which is better for quick, individual record retrievals. Regarding memory usage, ADW allocates a larger portion of memory to Process Global Area (PGA) to optimize complex query operations, while ATP allocates more to System Global Area (SGA) to optimize transaction processing and ensure efficient caching of the working set to avoid I/O operations.
To who, and in which order, are dedicated Exadata Infrastructure resources provisioned? (Choose the best answer.)
The correct order for provisioning Exadata Infrastructure resources is as follows: The Fleet Administrator provisions the Autonomous Exadata Infrastructure, which then provisions the Autonomous Container DB. Finally, the Database Administrator provisions the Autonomous DB. This order ensures proper allocation and configuration of resources from the infrastructure level down to the individual databases, aligning with Oracle's recommended practices.
Which two cloud services are supported to import data pump files from using Dedicated Exadata Infrastructure? (Choose two.)
The two cloud services supported to import data pump files from using Dedicated Exadata Infrastructure are Oracle Cloud Infrastructure Object Storage and Amazon S3. Oracle Cloud Infrastructure Object Storage is a primary storage service for data and object management in Oracle Cloud, and Amazon S3 is a widely used storage service by Amazon Web Services for object-based storage. Other options like Google Cloud Storage and Azure Blob Storage are not typically associated with Oracle's Data Pump import capability for Dedicated Exadata Infrastructure.
According to Oracle documentation, it is a best practice when planning and instituting Access Controls for your Autonomous Dedicated environment regarding
Subnets, Compartments and User Groups.
Which statement is true? (Choose the best answer.)
Oracle best practices recommend creating at least 2 of each resource: Subnets, Compartments, and User Groups. This approach helps in better organization and management of resources, improves security through segregation, and allows for redundancy, ensuring a more robust and flexible environment.
